Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.

**Horizontal Curves: Clearance Calculation**

To ensure safety on roadways with horizontal curves, it is crucial to maintain a clear area free of obstructions. The amount of space that should be cleared between an obstruction and the center of a roadway (measured in feet) is determined based on specific parameters such as lane width, design speed, and the radius of the curve.

### Problem:
Calculate the space that should be cleared for a horizontal curve with the following specifications:
- **Lane Width**: Two lanes, each 11 feet wide
- **Design Speed**: 67 miles per hour (mph)
- **Radius of the Curve**: 1,037 feet

**Input:**
- Design speed: 67 mph
- Radius: 1,037 feet
- Lane width: 11 feet (per lane)

**Task:**
Determine the clearance required between an obstruction and the center of the roadway.

**Note:**
The answer should be provided in feet.

### Formula:
To solve this, we would generally use roadway design charts or specific design formulas provided in transportation engineering guidelines. However, these details are not provided here, so specific equations cannot be shared.

**Please provide the calculation or use standard resources to determine the correct answer.**

Question The design speed of a highway is 80 km/hr and the radius of the circular curve is 150 m in plain topography. Which one of the following is the minimum length of the transition curve?
A curve of radius 250 ft and e 0.08 is located at a section of an existing rural highway, which restricts the safe speed at this section of the highway to 50% of the design speed. This drastic reduction of safe speed resulted in a high crash rate at this section. To reduce the crash rate, a new alignment is to be designed with a horizontal curve. Determine the minimum radius of this curve if the safe speed should be increased to the design speed of the highway. Assume fs= 0.17 for the existing curve, and the new curve is to be designed with e = 0.08
A vertical curve is to be constructed between a 2.5% grade and a -3.5% grade. The required sight distance is 305m. The dangerous object is considered to be on the pavement surface, and the driver's eye level is at 1.05m above the pavement surface. Determine the length of the vertical curve that will satisfy the sight distance requirement.
A horizontal curve is being designed to connect two tangents that intersect on a rural collector road with a specified design volume of 2500 veh/day (i.c. design speed 60 mph). It is expected that, because of right-of-way restriction, a large billboard will be placed at a distance of 50 ft from the centerline of the inside lane. If the terrain can be described as level and only a minimal amount of snow is expected on the road, determine the minimum radius of curve. Assume maximum superelevation rate (e) of 0.1 and fs=0.12. Ans: 1090 ft
A horizontal curve is to be designed to connect two tangents on a rural principal arterial with a design speed of 110 km/h. The station of the BC is 545+13.65. It is expected that an existing building will be located at a distance of 15 m from the centerline of the inside lane. Determine the minimum radius that will satisfy the sight distance and superelevation requirements.
